Bicycle wheel rim

Abstract

A bicycle wheel rim includes an annular rim body and a plurality of mounting members. The rim body has an axis, and includes a tire retaining portion which has annular left and right tire retaining walls that are spaced apart from each other. Each of the tire retaining walls has a radial inner edge proximate to the axis of the rim body, and a radial outer edge distal to the axis of the rim body. The rim body further includes an annular spoke mounting portion disposed radially inward of the tire retaining portion and interconnecting the radial inner edges of the tire retaining walls. The spoke mounting portion has two opposite lateral outer surfaces, and is formed with a plurality of receiving holes that extend through the lateral outer surfaces and that are distributed along the length of the rim body. The mounting members are received in the receiving holes, respectively. Each of the mounting members has two opposite mounting ends that project from the lateral outer surfaces of the spoke mounting portion. Each of the mounting ends is formed with a spoke mounting hole adapted for mounting a spoke thereon.

I claim: 
     
       1. A bicycle wheel rim adapted for mounting a plurality of spokes thereon, comprising: an annular rim body having an axis and including a tire retaining portion which has annular left and right tire retaining walls that are spaced apart from each other, each of said tire retaining walls having a radial inner edge proximate to the axis of said rim body and a radial outer edge distal to the axis of said rim body, said rim body further including an annular spoke mounting portion disposed radially inward of said tire retaining portion and interconnecting said radial inner edges of said tire retaining walls, said spoke mounting portion having two opposite lateral outer surfaces, and being formed with a plurality of receiving holes that extend through said lateral outer surfaces and that are distributed along length of said rim body; and   a plurality of mounting members received in said receiving holes, respectively, each of said mounting members having two opposite mounting ends that project from said lateral outer surfaces of said spoke mounting portion, each of said mounting ends being formed with a spoke mounting hole adapted for mounting a respective one of the spokes thereon.   
     
     
       2. The bicycle wheel rim according to claim 1, wherein said spoke mounting portion of said rim body includes annular left and right side walls formed with said lateral outer surfaces, said left side wall extending radially inward from said radial inner edge of said left tire retaining wall, said right side wall extending radially inward from said radial inner edge of said right tire retaining wall, each of said receiving holes being formed through said left and right side walls. 
     
     
       3. The bicycle wheel rim according to claim 2, wherein each of said left and right tire retaining walls further has an intermediate portion between said radial inner edge and said radial outer edge, said tire retaining portion of said rim body further having an annular connecting wall which interconnects said intermediate portions of said left and right tire retaining walls.
